Abstract: ABSTRACT OF THE DISCLOSURE In an electron accelerator having a target which is exposed to an electron beam for the production of x-ray deceleration radiation, a conical compensating member is arranged centrally within a cone pattern of the x-ray radiation.  The compensating member has a decreasing conical shape toward the target and merges into a cylinder portion.  Beam paths within the cylinder portion which are additional to those in a conventional purely conical compensating member are compensated by a recess positioned in a base of the compensating member having an appropriately selected depth.  In another embodiment, a conically shaped compensating member is arranged within the cone-shaped x-ray pattern such that a tip of the compensating member is aligned from the target and a base is aligned toward the target.  A colli-mator having a conical passageway surrounding the x-ray radiation has a groove for receiving the base of the compensating member so as to mount the same within the conical passageway of the collimator.

Abstract: ABSTRACT OF THE INVENTION Isobutane is injected into a liquid mixture concurrently with the injection of an oxygen-containing gas. Molybdenum catalyst is present. The oxidation is selective for the formation of tertiary butyl alcohol (TBA) so that the proportions of tertiary butyl hydroperoxide (TBAP), acetone, methanol, carbon dioxide or other less desirable products are relatively low. The tertiary butyl hydroperoxide produced by the reaction and/or the di-tertiary butyl peroxide in the reaction mixture remain in the reaction mixture while continuously distilling a product stream rich in tertiary butyl alcohol and those components boiling below TBA. After appropriate processing, such product stream is utilized as a blending component for gasoline.

Abstract: ABSTRACT OF THE DISCLOSURE       In accordance with an illustrative embodiment of the present invention, a drill stem testing apparatus that utilizes upper and lower inflatable packer elements to isolate an interval of the borehole includes a unique pump system that is adapted to supply fluids under pressure to the respective elements in response to manipulation of the pipe string extending to the surface.  The pump system includes a first pump assembly that is operated in response to rotation of the pipe string for in-flating the lower packer element, and a functionally separate second pump assembly that is operated in response to vertical movement of the pipe string for inflating the upper packer element. The rotationally operated pump assembly is uniquely designed to limit the inflation pressure that is supplied to the lower packer, whereas the inflation pressure generated by the vertically operate pump can be monitored at the surface.

The valve has a metallic needle that is axially movable and normally mechanically biased closed so as to rest on its seat.  The valve body is metallic as is also the spring that biases it closed.  Fuel pressure opens the valve when the injection pressure reaches a predetermined level.  The bias spring only (at one end) is electrically insulated from the valve body, and there is an electrical circuit connector to the spring so that a test signal is created when the needle breaks contact with the valve seat.

Abstract: ABSTRACT OF THE DISCLOSURE      A device for axial shirring of synthetic tubular material by forming a continuous helical fold.  As the unshirred tubular material moves along a mandrel, it is engaged by the teeth of at least three shirring tolls having their axes located in a plane transverse to the mandrel.  This assembly of shirring rolls revolves about the mandrel axis and the individual shirring rolls have peripheral teeth parallel to their respective axes.  The shirring rolls are interconnected for timed rotation with each other and preferably they are all driven from the assembly revolving drive means.  The teeth of the rolls have arcuate recesses or grooves which correspond to the mandrel surface, which overlap each other circumferentially about the mandrel surface, and which are so positioned about their respective axes that the teeth of any given shirring roll directly follows a tooth of the pre-ceeding shirring roll taken in the direction of revolution and in the direction of advance of the tubular material.

Abstract: Abstract of the Disclosure An air-sparged hydrocyclone apparatus and method, the apparatus including a substantially hollow, cyclone body having a cylindrical section and a downwardly oriented conical section.  An inlet, an overflow and an underflow are also provided in the cyclone body.  At least a portion of the wall of the cyclone body is modi-fied to include an air-sparging section wherein air, under pressure,  is  forced into the interior of the cyclone body as a plurality of bubbles.  The bubbles disrupt  the boundary  layer,  freeing entrapped  fine particles  and  also  assist  in carrying hydrophobic particles to the overflow.  The introduction of discrete, small, air bubbles is enhanced by forming a portion of the wall of the cyclone body from a porous material.

Abstract: FILTER PLEAT SUPPORT MEANS     ABSTRACT     This invention comprehends a new and unique means for preventing the crowns (forward projections of the pleats) of a backflushable filter element from splitting due to the cyclic action that is experienced during cleaning and backflushing.  In one embodiment, a plurality of spacers, preferably wedge shape, is positioned between the outwardly projecting pleats of the filter media thereby preventing the splitting thereof.  A plurality of spacers may also be placed between the inwardly projecting pleats to provide additional support during the cleaning and backflushing cycle.  In another embodiment a ring is placed adjacent the inwardly directed pleats and the inner end cap lip; this also prevents splitting of the crowns when the filter element is subjected to the cyclic action of cleaning and backflushing.

Abstract: Abstract:    A valve operating push rod for an internal combustion engine comprises a metal tube having end members with outer hardened surfaces of arcuate shape welded to the respective ends of the tube.  A tubular metal member having a length slightly shorter than that of the tube is pressure fitted inside or outside the wall of the tube. At least one of the ends of the tubular member is spaced apart from the welded portion between the tube and the corresponding end member.  The problem of vibration between the valve head and valve seat of the intake or exhaust valve of the engine can be minimised in this way due to the different individual vibrations of the tube and tubular member, since at least one end of the tubular member is not in contact with the corresponding welded portion.

A rail extends along each longitudinal side edge of each panel and has therein a plurality of spaced, parallel, longitudinally extending recesses, which open at opposite ends on inclined, plane surfaces that are formed on opposite ends, respectively, of each panel.  The inclined ends of the panels are secured together by four right angular corner clips at each end of the housing.  The two legs of each clip project slidably and frictionally into a pair of registering openings formed in the two panels which form a given corner of the housing.   A metal strap or handle extends transversely across one end of the opening in the housing and has rolled en-d edges which are slidably mounted in a pair of confronting, generally circular recesses that are formed in the side rails of the panel.  The outer end surfaces of the rails have therein registering recesses which form a rectangular, outwardly facing channel at end of the housing, and in which is seated a resilient gasket material which is used sealingly to connect opposite ends of the housing in a conduit or the like.

Abstract: CATHETER WITH TRANS-LUMINAL         GAS PATHWAY     Abstract A catheter having at least two separate lumens, one for conveying liquids to and from a port spaced substantially from the distal end of the catheter and the other for enclosing an electrical conductor which extends to a point distal to the port.
